I would definitely come back here if I needed it (I live in Fairbanks, and I was in the Anchorage area for a long-recovery medical operation during these necessary fixes). Also, I would vouch for the quality of workmanship and general professionalism of this business overall. Finally, the family-run ambiance of this mechanic shop is always refreshing, as I'm personally used to American-corporatism, an experience I earned from recently spending at least ten years in the lower 48.

Dropped our truck off on 1/8/2026 with a scheduled appointment to have the differential looked at…read more Agreement when I dropped off the truck was updates as the process is going on and that the truck would be ready on 1/21, the updates did not happen and still waiting to find out if the truck will be ready. Called on Thursday morning on 1/15 for an update, no service advisor available, message left with nice lady who answered the phone and someone would call me back. No call back. Called again on Monday morning 1/19 and again, no advisor available, message left and someone will call me back. Again, no call back. Called Tuesday morning 1/20, no one available and someone will call me back. Did get a call back and was advised that they just found out from my warranty company that the part is not covered. Asked when was the claim filed, last week I was told when the truck was looked at and the warranty company just got back to them today. I asked why not call me when you found out, busy was the response. Got off the phone with the warranty company and could not call the client right away to let me know. I called the warranty company and tracked the claim on line, the claim was not filed until today, 1/20 and response was almost immediate according to warranty company agent. So, no keeping the client up to date with what was going on, no returning calls and giving misguided information to when the claim was filed. Have my truck for almost 2 weeks with nothing being done to it. Their Customer Service needs some major help. Treat people the way you want to be treated when you are having something serviced. Be respectful of people.

If you go to Master Auto all you're going to get is empty pockets, they are charging $170 an hour…read morewhich they don't tell you when you drop off your vehicle by the way, I went in there to have three things done one of them being somewhat major my tea case needed split and a weak fixed. I told them it was because of a pinhole rubbing problem inside the t case that happens underneath the pump I told them exactly where it was going to be what the problem was everything the other two things were simply take a court of ATF out of my transmission and put a quart of Lucas oil stabilizer back in, and change my spark plugs and wires. When I dropped off my truck it had three quarters of a tank of gas, and I left them for 12 packs of soda for doing the complete job as a thank you now 2 Days later I get a call saying there's a hole in your TKS and there's nothing we can do about it, and do you realize how thick that Lucas oil stabilizer is his exact words were I am not going to sit here and watch it drain down the tube for 3 hours those were his exact words I'm sure he would have charged me for those 3 hours of sitting around too, so he denied to do that after accepting the job.. FYI you put the Lucas oil stuff next to something warm like in an engine bay and in 10 minutes, guess what it pours out just fine. They then told me I could come and pick up my truck it was ready to go and they had changed the spark plugs and wires. I got down there and he charged me just under $400 and in the end all that $400 got me was a plug in wire change out.. they put down 2.5 hours of Labor time just for the spark plugs and wires, and my truck went from three quarters of tank of gas to a quarter a tank of gas.. so what you guys do use my truck to run to the parts store all day? At $170 an hour none of this should have been an issue none of this should have taken place and I should have been able to go in pay what I was supposed to pay which would have been around 1,200 bucks and drive my truck home happy. Don't come to these guys unless you just need an oil change, battery change, oh and I guess we won't forget about spark plugs hahaha

Nick later told me that I didn't need an alternator replaced but instead a new battery. He then sent a new estimate which was even more than the previous one.

They charged me $400 to swap my car battery...that to me is outrageous !!!!
